CVE-2026-92554: XSS (CVSS 6.1)

Description

The ShopLentor – All-in-One WooCommerce Growth & Store Enhancement Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via Query-String Parameter Name in all versions up to, and including, 3.5.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The vulnerability is triggered via the WL: Product Horizontal Filter widget, which reflects attacker-supplied query-string parameter names from the current URL into option element value attributes without escaping, allowing payload breakout from the value="..." attribute context.
